ANIONIC POLYACRYLAMIDE - Santos

Anionic polyacrylamide is the copolymer of acrylamide and acrylic acid. No studies on the environmental fate of polyacrylamide are available. As a high-molecular weight, water-soluble polymer, it is not expected to biodegrade or bioaccumulate. Anionic polyacrylamide has a low acute toxicity concern to aquatic organisms.

tosan as a water clarifying agent (Prabhu et al. 1976) and as a flocculating agent in some industrial effluent treatment applications (Bough et al. 1976, Milazzo 1982). Aluminum salts are used as coagulants and hydrolysis products can be strongly adsorbed on negative particles and reduce their charge; this can be a major reason for the

Best Practices Guidance for the Use of Anionic Polyacrylamide

PAM aids solid-liquid separation by causing suspended particles to bind and form larger aggregates. The process is known as polymer bridging. One of the most common polymer flocculants on the market. Common uses of PAM as a flocculant: reduction of sediment and nutrient loads to natural lakes and ponds.

The resulting system was usually called ¡°water-soluble polymer dispersion¡± [8] or ¡°hydrophilic polymer dispersion¡± [9], and more usually, it was called ¡°water-in-water¡± (W/W) emulsion as it looked like emulsion in appearance [10-12]. For end use applications, such a dispersion can be either diluted with water, or just

Clarifying agents are used to remove suspended solids from liquids by inducing flocculation, causing the solids to form larger aggregates that can be easily removed after they either float to the surface or sink to the bottom of the containment vessel. Process

Adsorption of pyridine from aqueous solutions onto

The adsorption performance of pyridine onto polyaluminium chloride (PAC) and anionic polyacrylamide (APAM) water treatment residuals (WTRs) was investigated by batch experiments. This study confirmed the assumption that PAC¨CAPAM WTRs had the ability to remove pyridine.

Water treatment residuals produced after addition of polyaluminium chloride and anionic polyacrylamide (PAC-APAM WTRs) were evaluated for the potential to remove Cd2+ and Zn2+ from aqueous solutions by batch adsorption studies. The maximum adsorption capacity obtained from Langmuir modeling was 85.5 mg Cd2+/g PAC-APAM WTRs or 25.6 mg Zn2+/g PAC-APAM WTRs. A Dubinin-Radushkevich (D-R) model
